۞ God is the Light of the heavens and the earth. The parable of His light is, as it were, that of a niche containing a lamp; the lamp is [enclosed] in glass, the glass [shining] like a radiant star: [a lamp] lit from a blessed tree - an olive-tree that is neither of the east nor of the west the oil whereof [is so bright that it] would well-nigh give light [of itself] even though fire had not touched it: light upon light! God guides unto His light him that wills [to be guided]; and [to this end] God propounds parables unto men, since God [alone] has full knowledge of all things. 35 In houses which Allah has permitted to be exalted and that His name may be remembered in them; there glorify Him therein in the mornings and the evenings, 36 people who are not distracted by trade or commerce from the remembrance of God and the observance of prayer and the payment of the zakat -- fearing a Day when hearts and eyes will be convulsed, 37 (And they behave like this) so that Allah may reward them for their excellent deeds and, in addition to it, show His favour to them out of His bounty: Allah provides without stint for anyone He pleases. 38 But as for those who are bent on denying the truth, their [good] deeds are like a mirage in the desert, which the thirsty supposes to be water - until, when he approaches it, he finds that it was nothing: instead, he finds [that] God [has always been present] with him, and [that] He will pay him his account in full - for God is swift in reckoning! 39 Or, they are like darkness upon a deep sea covered with a wave above which is another wave, above which are clouds, darkness piled one upon the other; when he stretches out his hand he can scarcely see it. Indeed, to whomsoever Allah assigns no light, he shall have no light. 40
